Photovoltaic Generation Dataset from the Federal Institute of Espírito Santo, Serra, Brazil

This dataset comprises historical records of photovoltaic generation in the city of Serra, ES, Brazil, obtained through automated web-scraping scripts from two distinct sources: KSTAR (referring to the Laboratório Espaço Energia — Casa Solar — 3.0 kWp) and SolarPortal (referring to the main generation panels of the Ifes Campus Serra photovoltaic plant — 119.0 kWp). For the Ifes plant panels, the raw data covers the period from January 2023 to July 2025, whereas for the Casa Solar, the available records span from September 2023 to July 2025.

Additionally, a set of processed data was produced, also through automated scripts, covering the period from December 2024 to July 2025. In the case of the Ifes plant solar modules, raw measurements were provided on a weekly basis from January 2023 until November 2024, after which they were made available exclusively in daily format. A unified version of the processed data is also available, consolidated into a single .csv file for each source.
